Umorzenie postępowania karnego na podstawie art. 59a k.k. – wybrane zagadnienia

2016

Discontinuation of proceedings under Article 59a of the Criminal Code is a new institution in Polish criminal law. This article discusses selected issues relating to the premises for the application of Article 59a of the Criminal Code in practice. In view of the use by the legislator in Article 59a of the Criminal Code of concepts with vague meanings, their possible interpretations were proposed. It has been suggested that a rephrasing of the provision in ąuestion should be considered, in order to ensure the possibility of applying the said institution to a wider range of misdemeanours, as compensatory discontinuation is intended by the legislator to fulfil the redress function of proceedin…

Sulla storia dell'editto 'De pecunia constituta'

La dirigenza pubblica: criteri di identificazione e specialità della disciplina.

Nel tentativo di far luce sui maggiori coni d’ombra che emergono dalla relativa disciplina speciale del rapporto di lavoro, la tesi riflette l’esigenza di un ripensamento sistematico della figura del dirigente pubblico, nell’ottica di prospettare de iure condendo possibili correttivi. A tal fine, sono analizzate le peculiarità ed attribuzioni della dirigenza pubblica, in chiave storico-evolutiva, alla luce dei principi costituzionali e del processo riformatore che ha contrassegnato la magmatica materia, a tutt’oggi in atto. E’, altresì, rivolto uno sguardo comparativistico alla disciplina del personal directivo español, rivelandosi la stessa, speculare a quella del dirigente italiano quanto…

The influence of somatic cell count on sheep milk composition and cheese-making properties

2005

Somatic cell count (SCC) is an important tool for monitoring intramammary infections in dairy cows. However, systematic generalization of this decision rule is not easy in small ruminants. Determination of SCC in sheep milk is important for the processors of milk (indicator of quality), for breeders (mastitis indicator) and could be useful for selection as well. SCC value can be affected by some non-infective factors such as breed, stage of lactation, parity, type of lambing, type of milking, etc. (Bergonier et al., 1994), as well the health status of the udder (Fruganti et al., 1985; Ranucci et al., 1988). In addition, EC Directive 92/46, which regulates the production and commercialisatio…

Novel functional chitosan and pectin bio-based packaging films with encapsulated Opuntia-ficus indica waste

2021

Abstract The aim of this work was to study the effect of adding red prickly pear, as wasted source of antioxidants on various characteristics of novel functional (antioxidant) chitosan and pectin film formulations. Four types of prickly pear material were used: fruit pulp or peel, as powdered extracts and as aqueous extracts. Prickly pear peel extract was shown to possess higher antioxidant properties than fruit pulp. The antioxidant power of extracts was pretty high, around 1000 mgAAE∙100 g−1 for extract and that of all films around 100 mgAAE∙100 g−1 for films. Even though some changes in thickness, moisture content, water solubility, oxygen permeability and water vapor permeability of fil…

The influence of Opuntia ficus-indica mucilage edible coating on the quality of ‘Hayward’ kiwifruit slices

2016

Abstract The aim of this work was to study the effect of mucilage edible coating extracted from Opuntia ficus-indica (OFI) on the quality and shelf life maintenance of packaged kiwifruit slices. OFI mucilage alone or added with TWEEN ® 20 were applied on kiwifruit fresh cut surfaces. After treatments, kiwifruit samples were stored under passive atmosphere at 5 ± 1 °C for 3, 5, 7 and 12 days. At each storage period, visual quality and flavor score, pectin content, ascorbic acid and the microbiological characteristics were measured together with CO 2 and O 2 content in the packages. Kiwifruit slices coated only with mucilage or with mucilage plus Tween 20, showed a significant higher firmness…

Pellets based on polyuronates: Relationship between gelation and release properties

2017

International audience; Three polyuronates: amidated low methoxyl pectin (ALMP), low methoxyl pectin (LMP) and polygalacturonic acid (PGA) were used to encapsulate rutin in pellets, and they were characterized by different techniques (macroscopic properties, Calcium and rutin release). The ability of the three polyuronates to bind calcium ions and the viscoelastic properties of gels were performed to relate the properties of the pellets to the gel structures. The pellets size, the water content, the water uptake, the release of calcium and rutin varied depending on the polyuronate used. The pellets size of ALMP were smaller than LMP and PGA with a lower water content, but this matrix was mo…

Integral Extraction of Opuntia ficus-indica Peel Bioproducts via Microwave-Assisted Hydrodiffusion and Hydrodistillation

2019

The microwave-assisted hydrodiffusion extraction process affords high quality pectin and betanin from the peel of red and green Opuntia ficus-indica fruits under mild conditions. An aqueous mixture of valued bioproducts is readily obtained from the fruit peel cell water itself, without any water addition. The integral extract can be used as such to formulate nutraceutical beverages and products or, upon straightforward separation, to isolate pectin and betanin devoid of chemical contaminants suitable as ingredients for products ranging from food and beverage to cosmetic and pharmaceutical sectors. Betanin shows exceptional stability thanks to the high amounts of antioxidant polyphenols in t…

Biomaterial-Assisted Anastomotic Healing: Serosal Adhesion of Pectin Films

2021

Anastomotic leakage is a frequent complication of intestinal surgery and a major source of surgical morbidity. The timing of anastomotic failures suggests that leaks are the result of inadequate mechanical support during the vulnerable phase of wound healing. To identify a biomaterial with physical and mechanical properties appropriate for assisted anastomotic healing, we studied the adhesive properties of the plant-derived structural heteropolysaccharide called pectin. Specifically, we examined high methoxyl citrus pectin films at water contents between 17–24% for their adhesivity to ex vivo porcine small bowel serosa. In assays of tensile adhesion strength, pectin demonstrated significant…

Maltose-conjugated chitosans induce macroscopic gelation of pectin solutions at neutral pH

2014

Injectable polymer scaffolds are particularly attractive for guided tissue growth and drug/cell delivery with minimally invasive intervention. In the present work, "all-polymeric" gelling systems based on pectins and water-soluble maltose-conjugated chitosans (CM) have been developed. Maltose-conjugated chitosan has been synthesized at three different molar ratios, as evaluated by FITR analysis and fluorimetric titration. A thorough rheological characterization of the blends and their parent solutions has been performed. Macroscopic gelation has been achieved by mixing the high esterification degree pectins with CM at higher maltose grafted to chitosan contents. Gels form in a few minutes a…
